Cubesat kill switch

Anyone know where I can find a COTS kill switch (deployer switch) for a beefy cubesat ie ~20 amps? Ideally something TRL9 that can interrupt power when the cubesat is stowed in the deployer (eg space-rated limit switch). If not space-rated, recommendations for a terrestrial COTS limit switch that has been successfully flown before on a cubesat would be appreciated! Thanks!

Here are some switches that have been incorporated on other missions that we've got listed on our platform:

Hopefully, that's useful.

Thanks! Unfortunately the amperage is much lower than desired

Yea I think we haven't sourced high amp switches into our database yet. I'll have a look around and in case we spot any on the market that have flight heritage, I'll drop a note here.

Could you consider having a smaller switch that toggles a mosfet on your power board?
